He's been in love with technology since his earliest memories of writing simple computer programs with his grandfather, but his tech writing career took shape back in 2007 when he joined the Lifehacker team as their very first intern. Jason has over a decade of experience in publishing and has penned thousands of articles during his time at LifeSavvy, Review Geek, How-To Geek, and Lifehacker. Prior to that, he was the Founding Editor of Review Geek.

Of course there is still the possibility that the server 209.86.89.64 is innocent and only acted as a relay for the real attacker at 168.62.170.129, but then the relay is often considered to be guilty and is very often blacklisted. See, he is listed in 3 blacklists!
